IRANIAN asylum seeker Hamid Kehazaei, who died in a Brisbane hospital on Friday, will not have his organs donated, due to the illness he suffered leading up to his death.

Mr Kehazaei, 24, had been declared brain-dead at the Mater Hospital following the former Manus Island detainee's transfer from the Pacific International Private Hospital in Port Moresby, Papua New Guinea.

He had been on life support for a week prior to his death on Friday night.

Mr Kehazaei's family had requested his organs be donated once his life support system had been switched off, but doctors were unable to carry out that wish due to his septicaemia.

A Mater Hospital spokeswoman said she was unable to comment as Mr Kehazaei's death was now a matter for the coroner.
